THEODORE L. PATRICK, OF PAWPAW, ILLINOIS.

SASH-BALANCE.

Application filed March 11, 1915.

To all whom t may concern:

Be it known that I, THEoDoRn L. PATRICK, a citizen oit' the United States, residing at Pawpaw, in the county of Lee, State of Illi nois, have invented certain new and useful Improvements in Sash-Balances; and I do hereby declare the following to be a full, clear, and exact description o1 the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in windows and particularly to sliding sashes.

The principal object of the invention is to provide novel means which will take the place of the ordinary sash weights for balancing the window sashes.

Another object is to improve and simplify the construction of devices of this character whereby the sashes can be easily raised and lowered and can be readily taken from the iframe so that both sides of the glass can be cleaned.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is an elevation of a window frame and sashes made in acco-rdance with my invention, the sashes being shown in normal position, Fig. 2 is a vertical longitudinal sectional view on the line 2 2 of Fig. 1, Fig. 3 is a view similar to Fig. 2, the sashes being removed, and Fig. l is a vertical longitudinal sectional view on the line 1 -4l of Fig. 3.

Referring particularly to the accompanying drawings, 10-10 represent the vertical side portions of the frame of the window, 11 the heading and 12 the sill. On the inner faces of the side members are the usual parting beads 13 and the stops 111 and 15 respectively. Slidably disposed between the parting bead and the stops are the upper and .lower sashes 16 and 17, Formed through the sill, vat the edges and at points between the bead and the stops are openings 1S through which extend vertical rods 19 and 2O respectively. These rods are arranged to slide between the bead and stops and to engage with their upper ends against the lower sides of the two sashes. Below this sill, and under each of the openings 18 is a coil spring 20', the lower end of which Specification of Letters Patent.

is attached to a rod 19 while the upper end is attached to the underside of the sill, the rod passing through the spring. The normal tendency oit' the spring is to push upwardly on the rod and press against the sash so that it will be raised upwardly to the heading 11. At the upper rail of the lower sash 17 is a thumb screw 21 which passes tranversely through the rail and is adapted to be turned inwardly to bear against the tace of the lower rail of the upper sash, to hold the lower sash in lowered position. In this position the springs of the lower sash are extended, and the rods 19 pushed down through the sill, but when the screw 21 is loosened the springs will force the sash upwardly. The upper sash is normally held up by its rods 19 and when the upper sash is pushed down its springs are extended so that when the sash is released the springs push the sash into its upper closed position. The stops 15 are pivotally connected to the frame at their lower ends and are divided intermediate their ends, the upper portion of the lower sections being detachably Secured by means of thumb screws 22. By loosening these screws and swinging the stops into the room, the sash may be easily removed.

It will thus be seen that I have provided a simple device by means of which both sashes are normally 'forced into their uppermost positions, making it easy to raise either of the sashes.

What is claimed is:

The combination with a window frame and sash, of a sash balancing device comprising rods disposed vertically through the sill of the frame and loosely engaging the lower rails of the sashes, means on the lower rails for retaining the ro-ds in Vertical position, springs encircling the rods below the sills and having their respective ends secured to the sill and to the lower ends of the rods, and means carried by the lower sash for engagement with the upper sash to hold the lower sash in lowered position and maintain the springs thereof under tension.

In testimony whereof, I atlix my signature, in the presence of two witnesses.

THEODORE L. PATRICK.
